Anti-blocking device for drip irrigation

Abstract

The embodiment of the invention discloses an anti-blocking device for drip irrigation. The anti-blocking device for drip irrigation comprises a main box body, a pressure relief block base fixed in the main box body, a pressure relief block forming a pair of sliding pairs with the pressure relief block base, an annular rotating block forming a pair of rotating pairs with the main box body, and a worm arranged on the front side of the annular rotating block. According to the anti-blocking device for drip irrigation, the pressure relief block is used for blocking an annular blocking sleeve, so that a drip irrigation pipe can complete normal drip irrigation operation; when the drip irrigation pipe is blocked by silt, the water pressure in the drip irrigation pipe is increased, a limiting pin retracts into a limiting pin sliding cavity, and the pressure relief block moves rightwards to be away from the annular blocking sleeve under the water pressure effect of the drip irrigation pipe, so that pressure relief is completed, and the situation that a drip irrigation system is in a long-term state of overpressure and affects the service life is avoided; and meanwhile, the annular rotating block drives an inner barrel of the drip irrigation pipe to rotate by a certain angle and drives unblocked drip irrigation holes to rotate to the lower side of a drainage hole, so that the drip irrigation pipe can perform drip irrigation operation again.

Description

technical field [0001] The embodiments of the present invention relate to the technical field related to water-saving irrigation, and in particular to a device for drip irrigation and anti-clogging. Background technique [0002] The current drip irrigation system is equipped with a filter device, but in the long-term use process, there will still be sediment blocking the orifice on the drip irrigation pipe. After the small hole of the drip irrigation pipe is blocked, it will not only affect the watering and fertilization of crops, but also affect the long-term Blockage will also lead to excessive pressure in the water pipe and the drip irrigation pipe. Long-term overpressure will shorten the service life of the drip irrigation equipment, resulting in economic losses. Moreover, the current drip irrigation pipe generally does not have the function of preventing clogging. Once the blockage is serious, it needs to be replaced. tube, thereby affecting the efficiency of drip irrig...
